The invention provides a train wheel diameter calibration time prediction method and device, and the method comprises the steps: inputting a first wheel diameter time sequence of a train before the current moment into an ARIMA model, and obtaining a second wheel diameter time sequence of the train after the current moment, which is outputted by the ARIMA model; according to the moment corresponding to a second wheel diameter value smaller than a first preset threshold value in the second wheel diameter time sequence, the time for carrying out wheel diameter calibration on the train is determined; wherein the ARIMA model is obtained through training by taking the sample wheel diameter time sequence as a sample and taking a subsequent wheel diameter observation value sequence corresponding to the sample wheel diameter time sequence as a label. The determined vehicle diameter calibration time provides a reference for an operator to recalibrate the wheel diameter in advance, and timely recalibration is performed in a targeted manner, so that the train control accuracy is improved, and the train maintenance workload is reduced.
